[Purpose] This study aimed to investigate Japanese physical therapists’ attitudes of evidence-based practice and clinical practice guidelines. [Subjects and Methods] In 2014, a cross-sectional postal mail survey using a self-administered questionnaire was conducted. Of 2,982 physical therapists belonging to the Chiba Prefecture Physical Therapist Association, 1,000 were randomly selected. The questionnaire comprised 42 items pertaining to the attitudes of and behavior toward evidence-based practice and clinical practice guidelines. It was investigated to reveal the relationship between clinical practice guidelines/evidence-based practice and therapist characteristics. [Results] The response rate was 39.6%, and 384 questionnaires were available. The main results were as follows: 83.3% participants agreed to the importance of evidence-based practice, 77.1% agree to that evidence-based practice supports clinical decision of physical therapists, and about 11% agreed to have been educated about evidence-based practice. Then, 29.2% used, 54.9% agreed to the importance of, and 13.3% agreed to the utility of clinical practice guidelines. An important factor related mostly to a positive attitude, knowledge and behavior of evidence-based practice and clinical practice guidelines was participating in research activities. [Conclusion] Many of physical therapists do not use and understand the importance of clinical practice guidelines. Participating in research activities may partially contribute to improving these conditions.
In healthy subjects, dual hemisphere transcranial direct current stimulation (tDCS) over the primary (S1) and secondary somatosensory cortices (S2) has been found to transiently enhance tactile performance. However, the effect of dual hemisphere tDCS on tactile performance in stroke patients with sensory deficits remains unknown. The purpose of this study was to investigate whether dual hemisphere tDCS over S1 and S2 could enhance tactile discrimination in stroke patients. We employed a double-blind, crossover, sham-controlled experimental design. Eight chronic stroke patients with sensory deficits participated in this study. We used a grating orientation task (GOT) to measure the tactile discriminative threshold of the affected and non-affected index fingers before, during, and 10 min after four tDCS conditions. For both the S1 and S2 conditions, we placed an anodal electrode over the lesioned hemisphere and a cathodal electrode over the opposite hemisphere. We applied tDCS at an intensity of 2 mA for 15 min in both S1 and S2 conditions. We included two sham conditions in which the positions of the electrodes and the current intensity were identical to that in the S1 and S2 conditions except that current was delivered for the initial 15 s only. We found that GOT thresholds for the affected index finger during and 10 min after the S1 and S2 conditions were significantly lower compared with each sham condition. GOT thresholds were not significantly different between the S1 and S2 conditions at any time point. We concluded that dual-hemisphere tDCS over S1 and S2 can transiently enhance tactile discriminative task performance in chronic stroke patients with sensory dysfunction.
The parietal operculum (PO) often shows ipsilateral activation during tactile object perception in neuroimaging experiments. However, the relative contribution of the PO to tactile judgment remains unclear. Here, we examined the effect of transcranial direct current stimulation (tDCS) over bilateral PO to test the relative contributions of the ipsilateral PO to tactile object processing. Ten healthy adults participated in this study, which had a double-blind, sham-controlled, cross-over design. Participants discriminated grating orientation during three tDCS and sham conditions. In the dual-hemisphere tDCS conditions, anodal and cathodal electrodes were placed over the left and right PO. In the uni-hemisphere tDCS condition, anodal and cathodal electrodes were applied over the left PO and contralateral orbit, respectively. In the tDCS and sham conditions, we applied 2 mA for 15 min and for 15 s, respectively. Computational models of electric fields (EFs) during tDCS indicated that the strongest electric fields were located in regions in and around the PO. Compared with the sham condition, dual-hemisphere tDCS improved the discrimination threshold of the index finger contralateral to the anodal electrode. Importantly, dual-hemisphere tDCS with the anodal electrode over the left PO yielded a decreased threshold in the right finger compared with the uni-hemisphere tDCS condition. These results suggest that the ipsilateral PO inhibits tactile processing of grating orientation, indicating interhemispheric inhibition (IHI) of the PO.
Abstract.[Purpose] The purpose of this study was to elucidate how well patients' perceptions related to the improvements in their hand function during hospitalization.[Subjects] Sixteen patients who were hospitalized after hand surgery.[Methods] Using the Japanese Society for Surgery of the Hand edition of the Quick-Disabilities of the Arm, Shoulder, and Hand questionnaire; tactile roughness discrimination acuity, motor imagery, motor function, sensory function, and pain of the upper limb were assessed at admission and discharge. Spearman's rank-order correlation coefficients were calculated using the differences in all assessment items at admission and discharge. A multiple regression analysis (stepwise method) was performed to investigate factors that correlated with improvements in Quick-Disabilities of the Arm, Shoulder, and Hand scores.[Results] The improvement of tactile roughness discrimination acuity was significantly associated with patient perception of improved hand function. [Conclusion] The results suggest that an improvement in tactile roughness discrimination acuity was most strongly correlated with patient perception of improved hand function.
[Purpose] The purpose of this study was to investigate the degree of collaboration between practitioners and researchers through research papers related to the implementation of electrical stimulation (ES) for stroke patients. [Methods] A systematic review of the literature was conducted to collect data from ES studies published before January 7, 2015. Five databases were searched for search terms related to stroke and ES. Inclusion criteria were original papers that reported on ES of the upper or lower limbs following stroke, after the exclusion of case reports, brain stimulation studies, and papers written in any languages other than English or Japanese. The outcome was the prevalence of research papers that included a practitioner as an author, that included a practitioner as an author or in the acknowledgements, and in which the practitioner was the first author. [Results] Based on the selection criteria, 165 papers were included in the final analysis. The prevalence of papers in which a practitioner was included as an author was 39%. The prevalence of papers in which a practitioner was included as an author or in the acknowledgements was 50%. A practitioner was the first author of 34% of the papers. [Conclusion] Collaboration on research papers related to ES for stroke patients is limited.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
